TL;DR: Social organization and reproductive behaviour of Abudefduf zonatus were studied at Heron Island, Great Barrier Reef, and clustering behaviour may contribute to breeding syndrony in local populations.

TL;DR: Ratios of DDE to PCB in the more heavily contaminated egrets indicated that the birds had acquired the major part of their body residues on the wintering ground rather than in the immediate vicinity of the colony.

TL;DR: The foraging behaviour of the Reef Heron contains elements of hunting behaviour seen in many other species of heron, but relies mostly on a narrow range of techniques that minimize the problems created by the clear water and bright sunshine typical of coral reef habitats.
Abstract: The foraging behaviour of the Reef Heron contains elements of hunting behaviour seen in many other species of heron. None the less, the Reef Heron relies mostly on a narrow range of techniques that minimize the problems created by the clear water and bright sunshine typical of coral reef habitats. These make fish, which are the Reef Heron's principal food, difficult to approach and prevent the use of that classic hunting method of herons of 'stand and wait'. The particular behaviour used by a foraging Reef Heron is determined by the kind and size of prey, the conditions of the substrate and water, and the weather.

TL;DR: Agonistic behaviour and displays are described for foraging Reef Herons Egretta sacra, which defend foraging territories and this behaviour may be restricted to breeding birds.
Abstract: Agonistic behaviour and displays are described for foraging Reef Herons Egretta sacra. Displays are simple and are basically the same as described for other species and genera of herons. Reef Herons defend foraging territories and this behaviour may be restricted to breeding birds.
